Application filedv April 10, 1922.

To all 1072077). it may concern Be it known that I, lViLLnisi H. PEARCE, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented a certain new and useful Retaining Nut for Strips, of which the following is a specification.

My invention relates to retaining devices 1 best suited for holding metal strips on edge against plates or other metal parts.

The purpose of my invention is simply and cheaply to secure a nut to a metal edge so as to prevent the nut from turning and from moving transversely of the strip.

A further purpose is to anchor a retaining nut to the strip against movement longitudinally of the strip aswell as transversely thereof.

Further purposes will appear in the speci fication and in the claims. Y

I have preferred to illustrate my invention by two forms of nut only, selecting forms which have proved to be practical, efiicient and very inexpensive and which at the same time well illustrate the principles of my invention.

Figure 1 shows in perspective a gas stove top with gas-conserving plates to which a strip is attached by my invention.

F igure 2 is a bottom plan view of one of the plates in Figure 1.

Figure 3 is a section of Figure 2 on line 3-3 but right side up as in Figure 1.

Figure 4 is a perspective showing the device holding together perpendicular-plates.

Figure 5 is a perspective view of the nut shown in Figures 3 and 4.

Figure 6 is a perspective View of a modification of the nut shown in Figure 5.

Figure 7 is a perspective view of the metal strip with which the nut of Figure 5 or the nut of Figure 6 cooperates.

Figure 8 is a perspective showing the application of another form of nut.

Figure 9 is a perspective of the nut seen in Figure 8.

In the drawings similar numerals indi cate like parts.

In accordance with the statute I have illustrated my invention by the best application to it known to me which is the gas stove art in the holding of heat-conserving metal strips to the top plates of the stove, but I recognize that the invention is broader in its application than to this art.

Serial No. 551,048.

These metal strips have to be held on edge against the plate and difiiculty has been met in the past in doing this cheaply and effectively, and my invention when used in this art is applied to this duty.

In the first form shown the normal stove bolt 18 which passes through a plate at 19 is provided with a special nut 20 which is given suflicient width on one side as at 21 to extend across the metal strip 14. The nut is notched or grooved to'interlock with this 7 strip.

In the form of Figure 5 this notching is at opposite edges at 22 and interlocks with lat eral edges 23 of a slot 24 in the strip.

As will be seen relative longitudinal motion and relative lateral motion between the strip and nut are both prevented by simultaneous longitudinal and lateral interlocking at the slots, and at the same time the nut itself is held from rotation and definitely fixed with respect to the strip.

In the modification of Figure 6 the nut is notched on oneside only, to interlock longitudinally and laterally as before with the notch 24. While with this form lateral interlocking is only upon one side of the nut as compared with two sides with the form of Figures 4 and 5. yet it is evident that as in the first form the interlocking is such as si multaneously to clamp the strip to the plate. to lock the outer edge of the strip from either longitudinal or transverse motion and to prevent the nut itself from turning. A minor advantage from this interlocking is more easy assembly nuts being positioned for the bolts and more readily started in the bolts and held from turning while being tightened.

Making the slots 24 in the strips is an extremely easy and inexpensive operation, and the complete equipment is at once very simple and inexpensive and very eifective.

In the form of Figures 8 and 9 the nut is slotted at 25 across its face. and this form may be used without slotting the strip when it is deemed unnecessary to have the strip interlock longitudinallyas Well as laterally. The lateral interlocking without a mating notch on the strip maintains the strip vertiml with the plate.

and changes as come within the reasonable spirit and scope of my; invention. I

} Havingthus'describedjmy invention what I claim as new and desire to secure by Letters Patent is: i 1

1. In a retaining device a plate, a strip abutting the plateon one eoge and; havinga notch. in the other edge, a .b olt alongside the strip and. through the .plate and a nut on the bolt fitting within the notch.

2. In a 1etai ning device a plate, a strip having one edge abutting the plate and a notch in the otheredge, abolt along side. the strip andthroughthe plate, a nut on the bolt, and the nut having a notch adapted to lit and lock with thenotch of the strip to mutually lock. the strip andinut from relative. motion longitudinally of the strip and front relative motion transversely of the strip. v

3. In a. retaining device aplate, a strip having one edge on the plate and a notch in the other edge, a bolt along side the strip and through the plate, a nut on the bolt extending across the outer edge of the strip and'the nut having at the strip and longitudinal of the bolt a notch to fit and lock with the notch of the strip with mutual. locking between the nut and strip from relative motion longitudinally of the strip and from relative motion transversely of the strip.

i. In .a retaining device a plate. a strip having one edge on the plate andhaving a notch inits outeredge, a bolt along side the strip and throughthe plate, a nut on the bolt andhaving a portion across the outer edge of the strip and having notches at the strip on opposite sides of this portion and longitudinally of the bolt, and the notches of' the nut fitting and locking with the notch of the strip with mutual locking'between the nut and strip from relative motion longitudinally of the strip and from relative motion transversely of the strip.

5. In a retaining device, a plate, a strip intended'to abut with one edge against the plate and having a notch in its other edge, a bolt through the plate and a nut for the bolt having a'groove to receii'e the edge of the strip.

6. In a retainingdevice. a nut having a notch of substantially uniform width across one edge and to one side of the threading ot the nut.

7. In a retaining device. a nut l'aving opposite notches of substantially uniform width-across opposite edges and to one side of the threading of the nut.
